Just give us a minute to explain and all will become clear.

Obviously terminally cheeky ITV presenter Les Dennis has nothing to do with dubstep. He's only here to highlight the ingenuity with which musicians are using sampling.

Back in May 2009, Flux Pavilion (Circus Records) and Trolley Snatcha (now on Dub Police) decided to enlist the help (via YouTube) of the D-Man for their grimy banger Family Fortunes (DUBmented Beats).

Straight out of the light-hearted school of dubstep, who knew that a filthy synth replacing the ‘wrong answer’ noise from the show would be so funny.

The track will be the official theme tune for the next series.

Our survey said: 'Not really.'

L is also for:

LFO: Low Frequency Oscillator. Just assign this to the Filter Cutoff Frequency in your synth of choice, it's essential for making that dubstep bass sound.
